Mining (MNG)

Examination, development, and exploitation of mineral deposits; mining methods; unit operations; mining equipment; fundamentals of explosives.

The infrastructure of mines includes power systems, communication and tracking systems, and monitoring systems. Larger surface and underground mines often have power systems of similar size and complexity to a large town, but with additional engineering challenges created by the need to move the power system as mining advances, the confined spaces of underground mines, and the possible presence of combustible ores or explosive gases. Specialized communication systems are required in many underground mines because radio waves propagate poorly in these spaces. Personnel tracking systems are sometimes used to provide location information for all miners. Mine-wide monitoring systems are becoming increasingly common to improve personnel safety and equipment maintainability. In total, these mine electrical systems are a vital component of modern mines. Mining engineers take the lead role in the design and specification of these systems, just as they would for the materials handling, ventilation, and other ancillary systems of the mine. The goal of this course is to develop the necessary knowledge and engineering skills so that this work can be performed in a competent and safe manner. Circuit laws and network theorems are reviewed and the analysis of circuits is presented. The use of phasors and impedance diagrams, and the concepts of complex power and the power triangle are introduced. Models for two and three-winding transformers are presented, and the fundamental electromechanical concepts for motors and generators are given. The analysis of balanced three-phase is studied. Next, the basic concepts of power system protection are addressed. Grounding, ground bed design, and related topics are presented. Shock, fire, and explosion hazards are an everyday concern in mines, and the basic approaches for mitigating these hazards are covered. Distribution and utilization system arrangements, and the typical equipment for providing power within mines, are studied. Case studies from surface and underground mines are used to illustrate the concepts. The role of load flow and fault analyses in the design and operation of mine power systems is explained, and these concepts are applied using software tools. The application fundamentals of communications, tracking, and monitoring systems are presented, along with their operational advantages and limitations. The course culminates in a final project in which the mine electrical systems for a specific mine are designed.

A technical paper written on some field related to the laboratory and/or theoretical aspect of rock mechanics is required. A series of eight laboratory sessions are included. These give the students hands-on experience relative to the concepts and instrumentation problems discussed in lectures.

The mining industry consists of various stages of prospecting, exploration, beneficiation, development, and processing of naturally occurred solid minerals. These minerals include both metals (copper, iron, zinc, etc.) and nonmetals (coal, potash, limestone etc.), and all of these minerals are closely related to our daily life. For example, the coal still accounts for more than 50% of the electrical energy production. Both surface and underground mining has a long history globally. Modern techniques and large equipment have been applied in mining industry to increase the production effectiveness and create a healthy and safety environment in mining industry. This course offers an introduction to mining operations and related issues. The course will start with the role of minerals and mining in our daily lives and modern society. How should we classify and recognize different types of minerals beneath the earth? The course examines various stages of mining including prospecting, exploration, development, exploitation, and reclamation. From a mining engineer perspective, how to design a mining system form the beginning to the end. Common unit operations in mining, mining equipment, and some of the auxiliary processes are covered. Surface mining methods and surface mine development will be presented, as well the underground mining methods and the development of underground mines. The objective of this course is to introduce students to mining operations through study of basic concepts and equipment that facilitate the extraction of mineral resources. This includes learning about the stages of a mining project and life cycle of a mine, understanding the concepts of ore grades and reserves, mine development, mining methods, and unit operations that are essential to the operation of a mine. Through this course, students should build up the basic structure of mining industry, master the primary stages of developing a surface and underground mine, and enable to select a proper mining method based on the information of geology, deposit condition, mineral properties and so on. Equipment selection and capacity calculation at different mining stages is expected through learning in this course as well.

Underground mine design; extraction techniques; description of auxiliary operations as they relate to the mining methods. MNG 410 Underground Mining (3) The purpose of this course is to describe the logic and discuss the steps taken in the planning and design of an underground mine. Since every underground mine incorporates a unique combination of technological, economic, legal, social, and environmental factors, the course will stress the auxiliary operations (ventilation, ground control, etc.) which must be accommodated, as well as the unit operations and equipment dealing with resource extraction.
